In a half-pint (8 oz) mason jar, stir together milk, chia seeds, and maple syrup. Add cinnamon, oats, and diced pear, screw on mason jar lid tightly and shake!! (Alternatively, you could stir the ingredients together, but shaking will combine them more quickly!)
Set jar in refrigerator overnight.
Enjoy for quick and portable breakfasts!
Depending how large your pear is will depend on how much diced pear to use. Generally, it should be approximately one quarter to one half of a pear, cored and diced.
